Rotary Evaporator
A rotary evaporator is a machine used for the evaporation of liquids at low pressure. It is used in the laboratory to perform a variety of tasks, such as solvent removal, liquid fractionation, isolation of organic compounds and concentration of solutions. Although a rotary evaporator is a useful tool, it also represents an occupational safety hazard.
Because the device operates at low temperatures and pressures, it can produce cold steam and condensation, which can lead to burns and frostbite. In rare cases, the device can also explode. For these reasons, it is important to take a few safety precautions when using a rotary steamer…

Types of Rotary Evaporators your Laboratory may need
Vacuum Pump
Rotary evaporators are essential equipment in a laboratory setting for the efficient evaporation of solvents from samples under controlled conditions.

Our Rotary Evaporator best seller
Large capacity and large opening of evaporating flask give larger evaporation surface. The evaporating flask keeps rotating when it is constantly heated by water bath, and solvent evaporates more efficiently under vacuum condition. It can be used for pilot-scale production in biology engineering, pharmaceutical industry, chemical industry and food processing. It usually works with water circulating vacuum pump, diaphragm vacuum pump, recirculating chiller, constant-temperature circulator, low temperature circulating pump, etc.
Advantages
Patented technology of double sealing of Teflon(PTFE) and FV rubber ensures the negative pressure level.
Automatic switch valve makes continuous collection possible without affecting vacuum degree and without stopping distillation.
Teflon discharge valve is corrosion resistant and contamination free.
Water bath jacket protecting operator from scalding by hot liquid.
